Procedure

A mixture of 22.68 g of methyl [p-(phenoxy)phenyl]acetate, 17.195 g of N-bromosuccinimide and 20 drops of carbon tetrachloride saturated with HBr in 300 ml of carbon tetrachloride is heated at reflux for 28 hours. After cooling, the mixture is filtered through aluminum oxide, concentrated and distilled at 0.15 mm to give the product as a colorless oil (bp 162.5°-165° C).
